What else can I help you with?
In polar coordinates, the origin is called the?
pole
When plotting polar coordinates, the positive axis is called the ___ axis?
x-axis = polar axis
What equation describes the circle with radius 6 that is centered at the oridin?
The equation in Cartesian coordinates is x2 + y2 = 6 But much simpler are the polar coordinates: r = 6 and 0 ≤ q < 360 degrees.
X squared plus y squared equals 2y.change into polar equation?
x2+y2=2y into polar coordinates When converting Cartesian coordinates to polar coordinates, three standard converstion factors must be memorized: r2=x2+y2 r*cos(theta)=x r*sin(theta)=y From these conversions, you can easily get the above Cartesian equation into polar coordinates: r2=2rsin(theta), which reduces down (by dividing out 1 r on both sides) to: r=2sin(theta)
Which equation describes the circle with radius 7 that is centered at the origin?
The simplest formula, in polar coordinates, is r = 7.
What is the first number in an orderd pair called?
The abscissa in Cartesian coordinates. In polar coordinates, it would be the radius .or domain
True or False: One advantage of polar equations is that you can use a polar function to describe a graph whose equation in rectangular coordinates would not be considered a function?
True
What are absolute relative and polar coordinates?
absolute relative and polar coordinates definition
Write a c program to convert from cartesian to polar coordinates?
the equation that convert from cartesian to polar coordinates and vice versa r = sqrt (x*x+y*y); phi = atan2 (y, x); x = r*cos (phi); y = r*sin (phi);
How do you convert polar to rectangular coordinates?
If the polar coordinates of a point P are (r,a) then the rectangular coordinates of P are x = rcos(a) and y = rsin(a).
How can you determine the y- intercept if its not given directly?
The y-intercept (or y-intercepts) of an equation is where x = 0. Replace x with zero in the equation, and solve for y.The answer depends on what information you are given - and in what form. If the equation of the curve is given in polar coordinates or in parametric form, the process is quite different to that required when given the Cartesian equation.
What are 2 polar coordinates for the point 2 0?
The point whose Cartesian coordinates are (2, 0) has the polar coordinates R = 2, Θ = 0 .
